What's wrong with this? Ran this successfully on a Gentoo system, but now on a Debian-Squeeze (Raspberry PI) it won't work.

Database is setup allright

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| arduino1           |
| mysql              |
| performance_schema |
| test               |
| tmp                |
+--------------------+
6 rows in set (0.01 sec)

mysql>

Command is:

#mysql -u root -p******* arduino1 < arduino-tables.sql

Resulting in:

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(8),
    currentTime DATETIME,
    timeDiff INT(10),
    unixTime INT(10),
    currentR1 FL' at line 3

Content of arduino-tables.sql:

#cat arduino-tables.sql:

CREATE TABLE pulseLog (
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    timeStamp TIMESTAMP(8),
    currentTime DATETIME,
    timeDiff INT(10),
    unixTime INT(10),
    currentR1 FLOAT,

you are using keyword that is a datatype. you can do that by escaping it using backtick example

CREATE TABLE pulseLog (
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    `timeStamp` TIMESTAMP(8),
    `currentTime` DATETIME,
    `timeDiff` INT(10),
    `unixTime` INT(10),
    currentR1 FLOAT,
    currentS2 FLOAT,
    currentT3 FLOAT,
    currentAverageR1 FLOAT,
    currentAverageS2 FLOAT,
    currentAverageT3 FLOAT,
    temp0 FLOAT,
    temp1 FLOAT,
    temp2 FLOAT,
    temp3 FLOAT,
    temp4 FLOAT,
    temp5 FLOAT,
    pulses INT,
    event char(255),
 ) CHARACTER SET UTF8;
